LIQUIDrUELeBURNER VALVE. i

Application filed'september 24, 1925. 'serieilve 58,459.

i This vinvention relates to valves'for liquid VV fuelV burners and more' particularly to a lvalvefor employment in connection with a burner employedwherev fuel oil0 containing 5 foreign matter,` asfor example, acictsludge, is to 'bei consumed. Y While suchA fuels are economical to use, so V,far/as the costv thereof is concerned, nevertheless, .theyjare very difcult'to burnbecause of colin'g in the lo burner valves which y'interrupts Y'the operationof the burners.l Itis the practice tomix withl fuel oils of this low grade,fa certain percentage of a lighter yoil and yagitate e tllelnixture tov keep the sludge or other for- 7 eign matter in AsuspensionV so that such mah ter will not precipitate. The .addition-V of,

the lighter oil, however,7isV anfitem 'of exa fpense -and does notentirely eliminate the; .,coking of the fuel.l The presentV invention 2 0 therefore, has'as its'FpriInary-object to '.pro-

vide a valve for such a burner so con'structfk ed and operating automatically in such a rmanner,v as to entirely preventcolring of the fuel and provide for its `delivery tothe tially perfect combustion..A

As stated above, it isV customary to keep such .fuel in vcirculation and heretofore me-Qv chanical devices, operated exterior to the valve, have been employed vfor this purpose.

The present invention has, as anotherim-A portant object, to provide avalve so con-l structed that in its operation, coking ofthe l e -fuel and precipitation of the suspendedY sludge yor other foreign matter will be 'pre vented,and to provide yfor operation ofL this,

Y valvethrough the flowv'ofv the fuel through tlle fuelsupply pipe, from which it is dee livered,jby way of the valve,to `theburner, 40

fmechanically operated devices for effecting operation of the valve. r

, Another obj ect of theV invention is Vto so construct the valve that its component parts burner in a condition suitablefor substan-v thereby obviating thev employment of anyV fr may'be readily separated orydisassembled Figure 3 is a'view in side elevation ofV the valve 'stem actuating cam of'the'valve;f

Figure 4 is a perspective view of the member which coacts with the camfishown in Figure3. e 'e The casing'- of the kvalve comprises-two sections, oneA indicated in vgeneral by` the.

vnumeral '1 and the'other in general by the numeral 2.V vThe vsection lcomprises atubular body 3 threaded atA itsopposite ends 65 as at 4, to adapt it to be interposed inl the vfuel supply line' (not shown) vSand this body is formed ln its upper e. side with an openlngindicated by the'numeral 5, f

extending longitudinally of its VVintermediate 70 portion, and is further provided, eXteriorly, at opposite sides of theopening, with out- :standing longitudinal vflanges 6, the upper isldes of which Voccupy a 'comlrnonplane.A `The casing section 2 'comprises a 'substan- 75 A- tially. Vcylindrical hollow `body Vwhich isy relatively narrow and has an open bottom'and is provided yexteriorly with an'foutstanding yflange 7 matching the vflanges 6 of the casing section 1, bolts 8 'being secured through :80 e the flanges so as to 'separably' connect the .two sections of the: casingand thus support v thesecvtion 2 in upright posit-ionv upon the section 1, The section 2 ofthe 'casing is,"as 'y stated, of narrow., cylindrical Vformgalld com- 19" .prises a' circumferential vwall 9 and spacedl sidefwalls-lO'and 11. The wall 10 of the section`2 is formed or provided with a laterally extending short tubular boss 12 which is interiorlyfthreaded as indicated by themV .numeral 13, and into this boss there is fitted y one end of a cap member or bonnet 14 which j is formed with a borejlV having'squarerr'l threads'` 16 for a portion" of its length vand Ahaving 'appliedVV to its outer enda packing 95 nut 17 lwhich providesa fluid-tight fit about an adjusting stem 18 which is littedinthe said bore 15.@The stem 18V is provided, for

Aa portion of its length with squarefthreads f19 ittingtheuthreads 16,'andr atits outer 190 Aend is `]orovided7with a hand wheel by" jmeans fofv which itmay be rotated(v 'Y The Wall 11fof the valve casing is' prolrrrleel with e: lererelly prejeerirrg relatively -r Y short tubular extension 20 in vaxial alinement 10 with theextension `12, and a burner nozzle 21 of hollo'w'conical form is threaded onto the said extension 204 and'has a Vfuel orifice `22 at its outer or Vminor endrand which'is in axial @Heere-Il? with the were@ l?

'A spider j 23 is mounted Within the extension 20 and securely held in place and is provided centrally With an opening 24 in axial alinemen't With the orifice 22.r The valve body is indicated in general by the numeral 25 and the same comprises a cylindrical body portion 26 Which is both rotatably and slidably stem 28, the outer end `of which is presented portion and the threaded Astem is formed with numeral 30.

.portion of the stem finger 41 located at tending parallel with the portion 38 of the justing stein close to the inner end of the orifice 22, as best shown in Figure 1 of the drawings. At

a point intermediate its length, the valve body 26 is formed 'Witlra circumscribing shoulder v29 and from this shoulder to its other end, is threaded as indicated by the The numeral 31 indicates the hub of a fluid-impact Wheel or rotor embodying a. plurality of radial blades 32 which extend from the hub 31 and `Which are of ra Width somewhat less than the interior Width of the casing section 2. The hub 31 is threaded onto the threaded portion of the valve body 26 and abuts against the shoulder 29, and a cam element, indicated in general by ,the numeral 33 and illustrated in VFigure f3 ofthe drawings, is supported upon the threaded portion of the body 26, the said cam membercomprising a cylindrical body portion 34 interiorly threaded as indicated by the numeral 35, to fit the threads of the threaded portion of the valve body 26. The said body portion 34 of the cam member abuts against the hub 31 of the impact Wheel and the body is formed exteriorly with a circumferential cam rib V36 Which has substantiallythe form of a closed helix.

The threaded portion of the valve body 26 is formed interiorly With an axially extending bore 37, and at that end of the v,stem 18 which extends into the valve casing'is cylindrical and smooth and fits Within the said bore 37 as clearly shown in Figure 1 of the drawings. This portion of the stem is indicated by the numeral 38, and between this y portion 19, the threads 39,- and a collar 40 yis interiorly threaded and fitted onto this and is provided With a stem 18 and in close proximity to the lcircumferential surface of the cam vbody 34, the

finger having a notch 42 formed in its inner side Whichis presented toward the said cam body, toy accommodate the cam rib V36. It will ybe observed by reference to 'Figure 1 of the draw-ings, that the Vvalve body 26' vnot only rotatably `fits the portion 38 of the `ad- `tudinally thereon.

The autmatc valve embtlyng {hein-yen-V the periphery and ex- Y Y .l lclaim is:

1. A fluid fuel 'burner valve vcomprising a 18, but is also slidable longistood lthat there is, therefore, a constant fioW of fuel oil through the tubular body 3 of the casing section 1 of the valve and that inasmuch as the under side of the impact Wheel extends into the said body ofthe casing section 1, rotary motion will b e continuously impar-ted tothe said Wheel as the liquid fuel flows through the said casing section. As the impact Wheel rotates, rotary motion will, of course, v"be imparted to the valve-member 25 and, dueto the coacti'on of the cam rib 36 of the cam member'33 With the finger 41 of the collar 40, reciproca'tory lmotion will likewise be imparted to the said valve member 25 so that the extremity of its portion 28 will be. moved backvvardly and forwardly toward and from the fuel orifice 22 of the burn-er nozzle 21, thus agitating the vfuel passing through 'this orifice and preventing the accumulation o'f sediment or may be adjusted longitudinally, the valve' "member 25 may be bodily adjusted with relation to Ythe `orifice 22 so that the extremity of its portion 28 may be caused to operate at such a/distance from the orifice 22 as vto insure of the best results, depending upon the physical characteristics of thefuel oil to be consumed.

It will beV understood, of course, that, by

ies

adjusting the stem 18, `the flow controlli-ng portion 28 of the valve body '25 Will be fcor-y respondingly adjusted with relation tothe fuel outlet orifice 22, so as to control the flow of fuel through the orifice, it being=evid-ent that,'no'twithstanding the 'reciprocatory motion impartedl to the said lvalvebody, adjustment of the body as a Whole toward or from the orifice will respectively decrease or increase the flow of liquid fuel past the flow controlling portion 28`of the valve body and through the orifice.
